Did you know that every American president has worn glasses? Or that John Quincy Adams had a pet alligator that he kept in the White House bathtub? If you’re looking for quirky presidential trivia, try Stephen Spignesi’s Grover Cleveland’s Rubber Jaw & Other Unusual, Unexpected, Unbelievable but All-True Facts about America’s Presidents. For example, Millard Fillmore’s favorite color was fuchsia. Ronald Reagan was claustrophobic. A man once attacked Franklin Pierce and threw a hard-boiled egg at him. This book has all of the facts that you didn’t learn in U.S. history, but should have! Spignesi includes the good, the bad, and the just plain weird. It will appeal to presidential history buffs, as well as fans of trivia who just want to flip through the pages and have fun with history.

Those interested in a more serious look at the presidency should try The Presidents Club: Inside the World's Most Exclusive Fraternity. Nancy Gibbs and Michael Duffy, both editors at Time magazine, explore the relationships among the last 13 presidents. The book gets its title from the informal group jokingly named by Hoover and Truman. Now, it describes the bond that exists between former presidents regardless of their different political viewpoints. Many former presidents have assisted sitting presidents by serving as advisors or in diplomatic capacities. Reagan even stepped in to teach Clinton how to salute uniformed military personnel properly, and Clinton has developed a deep friendship with George H. W. Bush. In The Presidents Club, Gibbs and Duffy explore these little known connections and the history that created them.
